Electronic Structure and Chemical Bonding of Amorphous Chromium Carbide Thin Films
Martin Magnuson,Matilda Andersson,Jun Lu,Lars Hultman,Ulf Jansson
Physics , 2012, DOI: 10.1088/0953-8984/24/22/225004
Abstract: The microstructure, electronic structure, and chemical bonding of chromium carbide thin films with different carbon contents have been investigated with high-resolution transmission electron microscopy, electron energy loss spectroscopy and soft x-ray absorption-emission spectroscopies. Most of the films can be described as amorphous nanocomposites with non-crystalline CrCx in an amorphous carbon matrix. At high carbon contents, graphene-like structures are formed in the amorphous carbon matrix. At 47 at% carbon content, randomly oriented nanocrystallites are formed creating a complex microstructure of three components. The soft x-ray absorption-emission study shows additional peak structures exhibiting non-octahedral coordination and bonding.
A Review of Wavelets Solution to Stochastic Heat Equation with Random Inputs  [PDF]
Anthony Y. Aidoo, Matilda Wilson
Applied Mathematics (AM) , 2015, DOI: 10.4236/am.2015.614196
Abstract: We consider a wavelet-based solution to the stochastic heat equation with random inputs. Computational methods based on the wavelet transform are analyzed for solving three types of stochastic heat equation. The methods are shown to be very convenient for solving such problems, since the initial and boundary conditions are taken into account automatically. The results reveal that the wavelet algorithms are very accurate and efficient.
Transdisciplinarity as an Inference Technique to Achieve a Better Understanding in the Health and Environmental Sciences
Matilda Annerstedt
International Journal of Environmental Research and Public Health , 2010, DOI: 10.3390/ijerph7062692
Abstract: The problems of the world are not categorised into disciplines. They are far more complex, a reality that the tradition of transdisciplinary research has recognised. When faced with questions in public health and sustainability, the traditional scientific paradigm often seems inadequate, and, at least in medicine, transdisciplinary research has not yet been fully appreciated or acknowledged. This lack of recognition may be partly caused by a lack of cooperation between disciplines and between science and society. In this paper, I discuss some of the challenges that scientists and policymakers face in public health and environment within a methodological context. I present transdisciplinarity as a modern research tool that should be applied in research in health and the environment and argue that these topics can be approached beyond the inherent obstacle of incommensurability between disciplines. Thus, a small step might be taken in this immense research arena.

Studying young recipients of alcohol marketing - Two research paradigms and their possible consolidation
Matilda Hellman
Nordic Studies on Alcohol and Drugs , 2011, DOI: 10.2478/v10199-011-0039-7
Abstract: AIMS - The article discusses and compares two European studies that investigate young recipients of commercial messages on alcohol. The studies spring out of very different science philosophical paradigms. Their comparison therefore brings certain ontological, epistemological and methodological questions to a head. DATA AND METHODS - A large amount of existing research and theorizing has been reviewed in order to frame the studies concerning the following aspects: their goals (genesis, purposes etc.); their view on the nature of reality (ontology); their view on how knowledge is created and expanded (epistemology) and, their view on the role of values in research and theory building (axiology). RESULTS - It is suggested that although the studies work in separate paradigms and are concerned with different phenomena, they could gain from a consolidation for complementary purposes. CONCLUSIONS - The task of studying alcohol marketing audiences puts the alcohol research field's methodological capacities to the test. The field needs more interactive collaboration between different research traditions in order to produce credible research in this area.
Museums and the Intangible Heritage : the Case Study of the Afrikaans Language Museum
Matilda Burden
International Journal of Intangible Heritage , 2007,
Abstract: IntroductionTwo issues are addressed in this paper, namely the problem of representing heritage that is totally intangible in a museum ‘exhibition’, and the issue of the Afrikaans language and its place within the many officially recognized languages of the new South Africa. The two issues are linked in this analysis of the current exhibition in the Afrikaans Language Museum in Paarl, SouthAfrica.Having been involved in museums for the past two to three decades in different ways, from an academic as well as a popular viewpoint, in theory and in practice, I have always been very much aware of the importance of acknowledging and exhibiting intangible culture. I remain astonished that the literature on museums to a great extent still focuses very largely on material culture and in many cases totally ignores the existence of the perhaps intimately intangible culture. For example the Museums Association of the UK, still defines a museum as an institution which “collect, safeguard and make accessible artefacts and specimens [my emphasis], which they hold in trust for society”, while the International Council ofMuseums (ICOM) only added references to the intangible heritage and cultural centres to its definition of a museum in October 2004. However, on the positive side,the 2006 meeting of States Parties to the UNESCO Intangible Heritage Convention of 2003 nominated ICOMas one of five recognized expert non-governmental advisory organisations to assist in the implementation of the Convention.Languages are recognised in the Convention as one of the most important aspects of the intangible heritage of peoples, not just because of their intrinsic interest, but also because it is through language that so many important manifestations of the intangible heritage are transmitted from generation to generation.

Evaluation of large intestinal mucosa regeneration in ulcerative colitis using linear measurements
?olai Matilda
Medicinski Pregled , 2005, DOI: 10.2298/mpns0502011d
Abstract: Ulcerative colitis is a chronic inflammatory condition characterized by three phases: active, regression and remission phase. The active phase is followed by atrophy of the large intestinal mucosa. Although its evaluation is sometimes difficult, quantification of ceratin mucosal parameters can be used as an accessory method. The aim of the study was to determine the parameters of linear micrometry in order to estimate the regeneration of the large intestinal mucosa in ulcerative colitis, and to evaluate the efficiency of this method in everyday work. The measurements were performed on routine bioptic samples after qualitative histologic analysis and determination of the type and stage of the disease. The measurements were carried out to determine: the number of crypts per unit length, the height of crypt epithelium, diameter of crypts, their lumen and interstices; also, the quotient between the diameters of crypts and interstices was calculated. The analysis of the measured parameters points to presence and degree of regeneration and/or atrophy of mucosa, particularly by following the parameters of crypt epithelium. Linear measurements can be used in estimation of regeneration and atrophy of large intestinal mucosa. .
Risk-taking in a transitional economy: the case of Bulgarian microentrepreneurs
Matilda Alexandrova
Zbornik Radova Ekonomskog Fakulteta u Rijeci : ?asopis za Ekonomsku Teoriju i Praksu , 2005,
Abstract: The paper describes the results of an empirical study of some business environment factors impact on risk taking decision-making of entrepreneurs on the basis of individual entrepreneurial judgments. Multiple regression analysis is used to interpret data collected from 382 micro-entrepreneurs. It aims to answer the question of whether differences across economic environments may be reflected in entrepreneurs’ risk perception. Results indicate that environmental dynamism and uncertainty appear to have significant influence on risk-taking behavior being natively related to it. Some policy implications of this research are discussed in the context of conducted market transition reforms.
Scientific Annals of the Alexandru Ioan Cuza University of Iasi : Economic Sciences Series , 2011,
Abstract: IT outsourcing is among the prevalent practices in the global business today. It is found that business organizations decide to transfer such kind of services to other firms (identified as “vendors”) mainly because of cost-related advantages. It is still not clear whether the vendors are able to provide comparative advantages from the point of view of economizing costs of the production of these services. The objective of this paper is to identify the main determinants affecting the success of IT outsourcing partnership in Bulgaria on the basis of empirical study. The paper presents selected results from a survey of the outsourcing relations between Bulgarian vendor organizations and their clients (outsourcers) considering the issues of the development of successful strategic partnerships in outsourcing practices. In 2008 an empirical survey of outsourcing partnerships in 28 organizations providing high technology services has been conducted based on cases of Bulgarian vendor organizations. The subject of the study was the analysis of the key determinants influencing the formation and development of strategic outsourcing partnerships between Bulgarian vendor organizations and their clients (foreign companies).
